Add aws-evaluate-target-health flag

Updating CHANGELOG.md with 'Add aws evaluate target health flag' PR.

This is to add a new `--aws-evaluate-target-health` which allows the
user to override the default EvaluateTargetHealth value (currently set
to `true`) when creating AWS Route53 ALIAS records. To disable, pass
`--no-aws-evaluate-target-health` as outlined in the help page.

Closes https://github.com/kubernetes-incubator/external-dns/issues/627
